|---|---|---|---|---|---|
| Cell Membrane/Plasma Membrane | The outer lining of the cell. It separates the cell's internal structure from the external environment.
🗑
|
||||
| Selectively Permeable/Semi-Permeable | The cell membrane permits certain substances to enter and exit the cell which helps maintain the proper environment for the cell to function.
🗑
|
||||
| Diffusion | The movement of molecules or other particles in solution from an area of greater concentration to an area of lesser concentration until a uniform concentration is reached.
🗑
|
||||
| Osmosis | The movement of water or solvent through a semi-permeable membrane from an area of higher water or solvent concentration to an area of lower water or solvent concentration.
🗑
|
||||
| Solution | A homogenous mixture of two or more substances.
🗑
|
||||
| Homogenous | Pertaining to a solution, the substances are uniformly mixed and distributed.
🗑
|
||||
| Solvent | The part of a solution present in a great amount, the part that does the dissolving.
🗑
|
||||
| Solute | The part of a solution present in the lesser amount, the part to be dissolved.
🗑
|
||||
| What are the two parts of a solution? | Solvent & Solute
🗑
|
||||
| Osmosis can only occur when the membrane is permeable to ________. | water
🗑
|
||||
| Biconcave | Indented on both sides (think of life savers)
🗑
|
||||
| Isotonic Solution | A solution in which the total concentration of water molecules and solute molecules are the same on both sides of the semi-permeable membrane. Certain solutions are isotonic for certain cells.
🗑
|
||||
| Hypotonic Solution | A solution which has a lower concentration of solutes and higher concentration of solvent or water than the solution with which the cell is compared.
🗑
|
||||
| Hemolysis | The rupturing of a RBC as a result of hypotonic solution. Water molecules enter the RBC faster than they can leave, causing the cell to swell and burst.
🗑
|
||||
| Plasmoptysis | The rupturing of a bacterial cell as a result of hypotonic solution.
🗑
|
||||
| Hypertonic Solution | A solution which has a higher concentration of solutes and a lower concentration of water solvent than the solution with which the cell is compared.
🗑
|
||||
| Crenation | The shrinking of a blood cell as a result of hypertonic solution. The water molecules move out of the RBC faster than they can enter, causing the cell to shrink.
🗑
|
||||
| Plasmolysis | The shrinking of a bacterial cell as a result of hypertonic solution.
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
